Abstract: Embodiments of the present application disclose a photonic chip, a LiDAR, and a mobile device. The photonic chip has a substrate, a cladding layer, a first coupler, a first beam splitter, an emitting waveguide module, and a first optical adjusting monitoring module. The first beam splitter includes a first port, a second port, a third port, and a fourth port. The first beam splitter is configured to output the optical signal input through the first port through the third port and the fourth port, and to output the optical signal input through the third port through the first port and the second port. The first optical adjusting monitoring module includes a first photodetector. Monitors the optical power of the return light received by the emitting waveguide module through the first optical adjusting monitoring module integrated on the photonic chip, making the process more time-saving and labor-saving.
